(No model.)

To all whom it may concern:

Be it known that we,WILLIAM W. HOLSTON, residing at Morristowmin the county of Hamblen, and OZIAS L. FISHER, residing at Whitepine, in the county of Jefferson, State of Tennessee, citizens of the United States, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification.

This invention relates to improvements in metal railroad- 'es, having for its object to provide a tie combining the .advantages of the generally-adopted wooden tie together with a peculiar form of metal-tie structure.

The invention aims to provide a tie the parts of which may be very quickly assembled and placed in position and likewise readily removed whenever this becomes necessary, it being an essential object, however, to provide a tie which will be permanent relative to the longevity of the article.

For a full the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing the invention embodied in use. Fig. 2 is a sectional view through the preferred form of tie. Fig. 3 is a sectional view, similar to Fig. 2, of a modified form of tie. Fig. 4: is a detail perspective view of the end portion of the lower tie member, showing the exact form of the boxings disposed at either end thereof.

Fig. 5 is a detail view of one of the filler-blocks.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The ties consist of upper and lower members 1 and 2, each of the upper members comprising a plate 3, provided at each end with complementary boxings 4. The plates 3 or description of the invention and bodies of the members 1 and 2 are of metal,

and the boXings 4: and 6 are of integral formation with the body. In'the preferred form of the invention the boxings 4 are provided with outer ends 5, which ends inclose the inner boXings 6, carried by the lower tie members. The inner boxings 6 are closed at their inner ends, as shown at 7 and are adapted to receive filler-blocks 8, which are preferably of wood or material of analogouskind. In order to secure the filler-blocks within the in ner boxings 6 of the sides 9, the same are undercut and the sides of the filler-blocks 8 are outwardly inclined toward their lower side, so as to be securely held, so far as vertical displacement is concerned, within the boxings. To place the filler-blocks 8 within the said boxings, it is therefore necessary to give them a longitudinal movement from the open-end portions thereof. To prevent longitudinal dispacement of the blocks, the bodies of the upper members are provided with openings 10 adjacent the end portions thereof, which openings receive spikes or fastenings which secure the rails to the ties and which further, entering the filler-blocks, serve as means for holding the said blocks from longitudinal displacement from within the inner boXings.

The above applies as regards longitudinal displacement of a structureof the tie in which the outer boxings are not provided with ends. Of course it will be obvious that the fillerbloclzs will be prevented from displacement by the ends 5 of the boxings when the preferried form of tie, as shown in Fig. 2, is being USE The bodies of the upper tie members 1 are slotted longitudinally intermediate the end portions upon which the bo'xings are disposed, so as to add to the elasticity thereof, as will be readily comprehended.

Having thus described the invention, what 2. A railroad-tie comprising upper and lower members, each member consisting of amember, and filler-blocks disposed within the corresponding boxings carried by one of the aforesaid members.

3. In a railroad-tie consisting of upper and lower members, the lower member comprising a plate or body portion provided at its ends with boxings, filler-blocks disposed within the aforesaid boxings, the upper member consisting of a corresponding body portion provided at its ends with boXings to receive the boxings of the lower member.

4:. I11 a railroad-tie consisting of upper and lower members, said'members being provided upon their end portions with boxings, the body portions of the said upper members intermediate the aforesaid boxings being provided with openings therein.

5. A railroad-tie consisting of upper and lower members,said members comprising each a body portion provided atits ends with boxings, the said body portion of the upper members being provided with longitudinal openings therein intermediate the boxings carried thereby. 1

6. A railroad-tie consisting of upper and lower members, the lower member comprising a body or plate portion having boxings projected therefrom, the sides of the boxing-s being undercut, filler-blocks having inclined sides disposed within the said boxings, the upper member being provided adjacent its ends with corresponding boxings of a size to receive the boxings of the lower member, and means for preventing displacement of the filler-blocks from within the boxings of the lower member.

In testimony whereof we aifiX our signatures in presence of two witnesses.
